test(runtime-web): cover loadMetaModel in the browser-bundling gate

load-meta-model.ts imports metamodel constants from @metaobjectsdev/metadata/constants
to avoid pulling in the node:url dependency from the package root (#287). This test
uses Bun.build() to verify the bundle succeeds and contains loadMetaModel without
fileURLToPath, catching any future regressions where someone changes the import.
